Fledge cookie notice
Last updated: 21 August 2026
This notice is part of the Privacy Policy.
1. What this is about
A cookie is a small file a website stores in your browser. Local storage works on the same principle. This notice covers both.
Fledge barely uses cookies. Most of what is kept in your browser sits in local storage on your own device. We set five cookies: four are necessary for Fledge to work (keeping you signed in, remembering this device's sign-in check, your language choice, and your cookie choice), and the only optional one is for analytics.
2. What Fledge keeps in your browser
Necessary for Fledge to work
These are mostly kept in your browser's local storage. They stay on your device and do not travel to any other website.
| What | What for | How long |
|---|---|---|
scholar_token | Keeps you signed in | Until you sign out or clear your browser |
scholar_user | Your account details, so the app can show them without asking the server again | Until you sign out or clear your browser |
fledge_rt | Keeps you signed in on this device between visits. Only Fledge's server can read it (a cookie) | 60 days after your last visit (at most one year), or until you sign out |
fledge_dt | Remembers that this device confirmed a sign-in code, so next time your password is enough (a cookie). Signing out ends that trust for your account; the cookie itself stays in this browser, and any account that confirms a code here uses it too | 90 days |
fledge_lapsed | When your sign-in runs out, keeps your work on this device and your email for the sign-in form. Only your account can open it again | Until you sign in again or choose Not you, at most 90 days |
fledge_pending_next | Remembers which page you were going to while you reset your password | 2 hours |
fledge_signout_pending | If signing out could not reach our server, remembers to finish it next time | Until sign-out reaches our server |
fledge_browser_note_dismissed | Remembers that you closed the open-in-browser note | 14 days |
fledge_week:* | Your planned step for this week and the weeks you made a move, so Home shows them at once and offline. The step itself is kept by our server | Until you sign out or clear your browser |
fledge_home_seen:* | What Home showed at your last visit (your plan number, the stops you finished and which dates were on your calendar), so it can say what changed since | Until you sign out or clear your browser |
fledge_arrival:* | When you were last on Fledge on this device and when Home last greeted you, so coming back opens on your next move and a quick click does not. Times only, nothing about you | Until you sign out or clear your browser |
fledge_nav_essays | How many essays you have, so the menu knows whether to group the later pages | Until you sign out or clear your browser |
fledge_phone_taken | Remembers that the phone number you gave during the questions is already on another Fledge account, so Settings can tell you. It holds no number | Until you add a number, sign out or clear your browser, at most 30 days |
fledge_plan_notice | Remembers that this device showed the note about your plan now being built from your work in Fledge, so it shows once. A time only, nothing about you | Until you clear your browser |
fledge_promo | A promo code from a link you opened, so the checkout can apply it after you sign up. The code's text only | Until you pay with it, sign out or clear your browser, at most 30 days |
fledge_plan_welcome:* | Which plan notes you put away (a new plan), so they do not show again | Until you sign out or clear your browser |
fledge_plan_moments:* | Your plan's pace on this device: a "Busy until" date, the lighter plan, your answers to "Did you submit?", when you last opened your plan, and which notes after an offer you have already seen, so each shows once | Until you sign out or clear your browser |
fledge_locale | Remembers whether you chose Mongolian or English (both local storage and a cookie) | Local storage: until you clear your browser. Cookie: up to 12 months |
scholar_onboarding_state | Keeps the answers you started before creating an account | Until you register or clear it |
scholar_theme | Remembers your display setting | Until you clear your browser |
fledge_consent | Remembers your cookie choice: whether you accepted or declined analytics, and when | Up to 12 months |
Fledge does not work without these. Clearing your browser storage signs you out.
Kept only while the tab is open
These sit in your browser's session storage. Closing the tab forgets them.
| What | What for | How long |
|---|---|---|
fledge_first_week | Where you are in the first steps after sign-up, so a reload comes back to the same screen | Until you close the tab or sign out, at most 2 hours |
fledge_locale_synced | Remembers that this tab already told your account which language you use, so reminders come in it | Until you close the tab or sign out |
fledge_landing | How you first came to Fledge in this tab (a campaign tag, a referral code, the site that linked here), sent once to our server after you sign in | Until you close the tab, at most 1 day |
fledge_offer_placement | Where the Plus offer you pressed was, so the order says which page led to it | Until you close the tab or sign out |
fledge_onboarding_phone | A phone number you typed during the questions, until your account saves it, or that you chose not to add one | Until your account saves it, you close the tab or sign out, at most 2 hours |
fledge_account_switched | Remembers that this tab was signed in to a different account without you typing it in, so the page tells you which account it is until you answer | Until you answer the notice, close the tab or sign out |
Analytics: the only optional cookie we set
We use PostHog to understand which features people use, where they get stuck, and what breaks. That is how we decide what to do next.
| What | What for | How long |
|---|---|---|
ph_*_posthog | Recognises a returning browser so one visit is not counted twice. Records page views and feature use | Up to 12 months |
This cookie is set on your first visit and analytics runs from then, unless your browser sends a Global Privacy Control or Do Not Track signal, or you turn analytics off. Turning it off removes the cookie and stops the data.
Two things to know.
- PostHog runs through fledge.to, not from a separate domain. So this is not a third-party tracker; it is a cookie on our own domain. It cannot follow you to other websites.
- We use it to see overall patterns across many users. It does not build an advertising profile of you, and it is not sold.
No advertising cookies
Fledge does not show advertising and does not place advertising or targeting cookies.
3. Your choice
- Analytics: you can turn analytics off in the “Your choice” section of this page, or in your account settings. That cookie is used only for analytics, so with it off Fledge works exactly the same.
- Your browser: every browser can clear cookies and local storage. Clearing local storage signs you out and forgets your language choice. Nothing in your account is lost.
- Browser signals: if your browser sends a Global Privacy Control or Do Not Track signal, we treat it as a refusal and analytics stays off.
- Withdrawing consent: write to hello@fledge.to at any time.
Your choice
4. Changes
If we add a tool that sets cookies, we will update this notice and ask you again where consent is required.
